Wyoming WY Medicare Locality 21

MAC 03602 · Locality 21

This locality's GPCIs are all at or below the national baseline, so services priced with the standard RVU formula usually come out below the national amount for the Q3 2026 Physician Fee Schedule. For nationally priced services, Medicare adjusts each code's work, practice-expense, and malpractice RVUs using these indexes.

Work GPCI

1.000

Adjusts the physician-work component for professional labor costs

Practice expense GPCI

1.000

Adjusts practice-expense inputs such as staff, rent, and services

Malpractice GPCI

0.740

Adjusts the malpractice component using liability-cost data

1.000 is the national baseline. A value above 1.000 raises that component; below 1.000 lowers it. GPCIs are Medicare payment factors, not general cost-of-living or physician-compensation indexes.

Common questions Copy link

Why do Medicare rates in Wyoming differ from the national amount?

For nationally priced Physician Fee Schedule services, Medicare adjusts each code's work, practice-expense, and malpractice RVUs by this locality's three GPCIs before applying the conversion factor. Local costs for physician work, running an office, and liability insurance therefore move the final amount up or down. Wyoming currently has all three GPCIs at or below the national baseline, so services priced with the standard RVU formula usually come out below the national amount for the Q3 2026 release.

How do I know if my address is in this locality?

Medicare payment localities are geographic fee-schedule areas, commonly defined with county boundaries. CMS uses the ZIP code where the service was performed to assign a claim to its contractor and locality. Look up your ZIP to find your locality. About 7 ZIP codes in Wyoming span more than one locality and need the ZIP+4 to resolve exactly.

Do commercial insurers or Medicare Advantage plans use this locality?

Original Medicare uses these PFS localities directly. Commercial and Medicare Advantage plans are not required to use the same locality structure. A contract may pay a percentage of Medicare, but its own wording decides which Medicare release, percentage, geography, and adjustments apply.

Does my locality affect what I owe as a patient?

For a covered service, a higher allowed amount in your locality usually means a higher 20% coinsurance. The effect depends on the code, the beneficiary's deductible, supplemental coverage, and other claim circumstances.

Why did my Medicare payment change even though I didn't change what I billed?

CMS publishes updated PFS files during the year. A code's amount can change because of conversion-factor, RVU, policy, or correction updates. GPCIs are usually set once a year in the fee schedule rule, though later files can correct them. See what changed each release.

Source & method Copy link

We compute GPCIs and rates from the CMS Medicare Physician Fee Schedule Q3 2026 release (effective July 2026). ZIP coverage from the CMS ZIP-to-locality crosswalk, Q3 2026 release. Example amounts use the standard (non-QP) physician conversion factor ($33.4009) and apply this locality's GPCIs to nationally priced Office (non-facility) RVUs, before the ~2% sequestration cut. Past releases are never edited, so a rate for an earlier quarter always matches what CMS published for it.
